How many computers must the ab computer company sell to break even? let x be the number of computers.
cost function: c (x) = 145 + 1/4x
revenue function: r (x) = 1.5x

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

-----> equation A

----> equation B

where

C is the cost function

R is the revenue function

x is the number of computers sold

we know that

Break even is when the cost is equal to the revenue

so

equate equation A and equation B

Solve for x

subtract 1/4x both sides

Divide by 1.25 both sides

therefore

The Company AB must sell 116 computers to break even
